grm's questions

I'm trying to get xdg-open to open css files with correct editor, but can't get file to report correct mimetype for a file.css file. There is an entry both in /etc/mime.types and a file already exist as /usr/share/mime/text/css.xml but this always happens:

➜  ~  echo ". {}" > file.css
➜  ~  file --mime-type file.css
file.css: text/plain
➜  ~  

When I trace the code, I see that it uses magic instead of /usr/share/mime/text mime db. How can I get file to report this as text/css instead of text/plain?

I'm trying to get the command-not-found feature under Ubuntu to work under zsh, without luck:

➜  ~  pdfunite
zsh: command not found: pdfunite
➜  ~  bash
u@ub:~$ pdfunite
The program 'pdfunite' is currently not installed.  You can install it by typing:
sudo apt-get install poppler-utils

Does anyone know if there is a package available that also supports zsh?

Thank you.

I have a directory where many users have write access and often the permissions on the directory changes. Is there a tool that lets me monitor the files for changes and enforce a specific file permission or any other way I can enforce this when users have write permission.

I'm trying to install emacs24 for an external repository, but I receive an error regarding unmet dependencies and wonder how I can continue the installation and resolve this error?

The output looks like this:

dito@dito:~$ sudo apt-get install emacs-snapshot-nox

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

I'm trying to change the Preferred Application for email. I have installed the package desktop-webmail, but there is no new option under System - Preferences - Preferred Application as you would expect, infact, there is only one option there, only Evolution.

According to this post it should be possible to set a custom application, but no option is available.

Is it possible to setup GMail as Preferred email app so that File -> Send by email works in gnome apps?

This seems to be a dup of another post here, Thing is that this works fine in 10.10, but in 11.04 this method no longer work. My post above is meant for 11.04 and the question is still valid.

I have installed jwhois on many systems, but can't get it to work. The port 43 is open through the firewall and I can do a telnet to the whois server on port 43, but whenver I run jwhois I get the following error:

[Querying whoisserver]
[Unable to connect to remote host]

Any idea on how to fix this issue?

Considering that I run a low memory VPS, should I configure Apache to use mod_fcgi, PHP APC or both? As I understand it, the APC will not be shared between processes so I wonder what would produce the best result on busy sites: mod_fcgi, APC or a combination?

Lately, I have received errors while using wget against github on ubuntu 10.04.

ERROR: certificate common name `*.github.com' doesn't match requested host name `github.com'.
To connect to github.com insecurely, use `--no-check-certificate'.

Does anyone know why this error ocours and how to fix it (without --no-check-certificate).

Is there an easy way to install a MTA on Ubuntu and forward all email to a different remote email box? Only want to forward local email and looking for something dead simple. Thank you!

Clarification:

I see that ssmtp and nullmailer are suggested, but I need something (just a) little more clever. I have one machine (machine.domain1.com) where I want local mail to be delivered at [email protected] and I want it delivered through direct connection to mx.domain2.com

So when I do mail root on machine1.com it should get forward to [email protected]. Issue with nullmailer and ssmtp is that forwarding is done to mx.domain2.com but mail is delivered with a RCPT TO set to [email protected] and I want the RCPT TO set to [email protected]

Possible with a simple solution or do I need to digg into postfix or exim for this?
